I went to a local home and remodeling show this weekend. There were a few HVAC dealers there and most were touting geothermal. I spoke to a couple and when I referenced having a pond that is accessible for use, they were very helpful with tips on what they would like to see when the pond is renovated.
They have floated in the pipe before but having a clean bottom to work with was a much better situation. There have been problems/questions as to how well they could arrange the pipe array in the past and using spacers between loops is beneficial. They also would prefer to place the loops off the bottom for better circulation around the HDPE.
With the 30% federal tax credit and the state incentives, I can see no downside to going this route. Heck....I want to build this house just to use some of the newer technologies out there.
